Yes, you can use "svn log" to do the lookup of what revision corresponds to what date, or rather, what revision occurs immediately before the specified date. For example:

$ svn log -r '{2010-01-01}' --limit 1 -q \
http://svn.macosforge.org/repository/macports
------------------------------------------------------------------------
r62218 | portindex_at_macports.org | 2009-12-31 18:54:29 -0600 (Thu, 31 Dec 2009)
------------------------------------------------------------------------
$

(The last revision committed to the MacPorts repository before January 1, 2010 was r62218 committed the evening of December 31, 2009.)

To reduce this to just a revision number, I could use awk:

$ svn log -r '{2010-01-01}' --limit 1 -q \
http://svn.macosforge.org/repository/macports \
| awk '/^r/ {print $1}'
r62218
$
